Watershed Management Area 11
Central Delaware

Watershed Management Area 11, known as the Central Delaware Tributaries, affects the drainage in 24 municipalities within the counties of Hunterdon, Mercer and Monmouth. The predominant drainage funnels to the Delaware River or the D&R Canal. Watershed Management Area 11 covers approximately 272 square miles and is dominated by the Assunpink Creek and its tributaries to the south and much smaller creeks in the northern portions. Land uses in this area range from agricultural to urban, most notably in our State Capital, the City of Trenton. The land area has also been heavily impacted by suburban development. Population for this area over the past 10 years has greatly increased, with its development stressing water resources and impacting water quality.

There are 4 subwatersheds in Area 11 that include Lockatong Creek/Wickecheoke Creek, Hakihokake/Harihokake/Nishisakawick Creek, Alexauken Creek/Moore Creek/Jacobs Creek and Assunpink Creek.
